What is the use of pointer to object in C++?

A pointer to a C++ class is done exactly the same way as a pointer to a structure and to access members of a pointer to a class you use the member access operator -> operator, just as you do with pointers to structures. Also as with all pointers, you must initialize the pointer before using it.

How are pointers assigned to objects?

A pointer is a type of variable that carries location information. In this case, the example variable will store the address of an Order object that we want to interact with. We initialize the pointer variable by using the C++ new operator to construct a new object of type Order.

How do you explain pointers in C++?

Pointers are said to “point to” the variable whose address they store. An interesting property of pointers is that they can be used to access the variable they point to directly. This is done by preceding the pointer name with the dereference operator ( * ). The operator itself can be read as “value pointed to by”.

How do you initialize a pointer object in C++?

You need to initialize a pointer by assigning it a valid address. This is normally done via the address-of operator (&). The address-of operator (&) operates on a variable, and returns the address of the variable. For example, if number is an int variable, &number returns the address of the variable number.

How a pointer is declared and initialized?

Pointer is declared using special character ‘*’ along with datatype pointer points and name of the pointer as an identifier. Pointer initialization is a programming technique in which pointer is assigned an address of a varible so that pointer points to specific value.

How pointer is assigned to object explain with simple example?

Just like Other Pointers, the object pointers are declared by placing in front of a object pointer’s name. The Syntax is: class_name * Object_pointer_name; In above Syntax, class_Name is the name of an already defined class and object_pointer_name is the pointer to an object of this class type.
